The effects of carbonization temperature on some
physicochemical properties of Bamboo waste by the chemical
activation with potassium hydroxide have been investigated.
The bamboo based activated carbon was characterized in terms
of the yield rate, ash, porosity, density, and specific
surface area at different carbonization temperature in the
chemical activation process using standard methods of
analysis. The results showed specific surface area, density,
yield, moisture content porosity and ash content were
234m3/g, 0.483g/cm3, 32.67%, 0.74 and 2.92% respectively.
The metal contents present were Pb2+, Fe2+, Ni2+, Zn2+,and
Cd2+ with Z2n2+ having the highest concentration (
31.40mg/kg) and Cd2+(8.9mg/kg), the lowest. The yield rate
decreases with increase in temperature, while ash, density
and specific surface area increases with increase in
temperature. KOH activation of bamboo was suitable for the
preparation of charcoal which are essentially microporous.
